“…In the study, all of key subsystems and important subsystems [6] should be taken full into account, especially for key subsystems. Of course, if there is not only one mode by that all subsystems are organized to make the system reach optimum, the cost of every mode should be taken into account and the mode with the lowest cost should be chosen at the next steps.…”
In order to reveal the relationship between optimizing a certain function of system and optimizing the relevant functions provided necessarily by its subsystems to realize the function of system, this paper studies the systematic mechanism of the function of system not being equal to the sum of the relevant functions of its subsystems based on function additivity, and obtains some laws about optimizing system and its subsystems on condition that these functions are additive. In addition, it lays a foundation for the further research, i.e. how to ascertain the function provided necessarily by every subsystem and the value of it when we want a system or a certain function of it to be optimal.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
